Had a sporadic error occuring on my jdm sti5, whilst driving sedately there's no problem however often under hard acceleration the CEL will somtimes come on and restrict the car to 4.5k.
I've checked the code and its error 33.
So i replaced the speed sensor cleaned all the contacts and still have the same problem.
I've checked the the delimitor wireing and that appears fine has anyone known these circuits to fail?

Cheers
Chris
